Takata 5-pt. harness install

after two months of waiting for the crotch strap portion for a 5pt. Takata harness conversion, install pix for reference

Since I fabricated a custom seat bracket, I welded the nut that came with the eyebolt under the rear brace of the bracket instead of drilling a hole on the flooring just what like everyone suggests.

The position of the eyebolt is about 4"-5" away from where the hole on the bucket seat, notice the white line, that's the center of the hole of the bucket seat. This position gives me just about the right length for the crotch strap when fastened to the harness buckle.

The harness that I got was specifically for a two seater (part no. MPH341w) so length of the shoulder harness was not an issue

the installation of the side harnesses were pretty basic, the right eyebolt bolted to where the OEM seatbelt buckle was originally placed

nice "idea" but not legal for most any organization. they require it sandwhiched through the floor. at that point, your hoping that thin piece of 1/8 inch steel will actually hold you in place. if you've ever seen the aftermath of an on-track incident, you wouldn't even attempt this..

there's a reason why everyone "suggests" drilling through the floor. it's so you don't die when you actually need your harness.. ;)

That's a nice healthy moment arm on the weld in the case that high loads are applied to it. Same with the mounts on the upper cross-bar. At a minimum (and totally agreeing with NAautoxer that the only legit way to do it is a floor mount with sandwich plates), I would recommend a welded bracket that mounts the eye in-line with the load. You get a ton more weld area, and avoid side-loading the eye (take a look at the load rating on those, the side load is usually a fraction of the max rated in-line load).

Also the shoulder harnesses should be wrapped around the harness bar.

That looks extremely dangerous. And whats up with that harness bar?

Are you new to welding as well? Why did you weld in the non-contact surfaces? Your weld is held together with filler...
